Thread the tie-backs through the slots on the
ZMM and fix to the selected location on the
computer chassis. The tie-backs should
completely encircle the ZMM to ensure that it is
held in place securely, as shown at right. Be
careful not to restrict air-flow through your
system.

Connect your computer’s disk activity LED
cable to the LED connector on the controller (marked on the figures in
About Your RAID
Controller
on page 15
).
Ensure that the positive lead of the LED cable (usually a red wire or a wire marked with a
red stripe) is attached to pin 1.

Connect your RAID controller’s I2C connector to an I2C connector on an internal
backplane or enclosure, using an I2C cable. For more connection details, see
About Your
RAID Controller
on page 15
.

Prepare and install your internal disk drives, following the instructions in
Connecting Disk
Drives to Your Controllers
on page 38
.
If you are not installing internal disk drives, close your computer cabinet, reattach the
power cord, then continue with
Connecting External Devices
on page 40
.
Connecting Disk Drives to Your Controllers
You can connect SAS disk drives, SATA disk drives, or a combination of both to your SAS RAID
controller. (See
www.adaptec.com/compatibility
for a list of compatible disk drives.) There are
no jumpers or switches to set before installation.
If you plan to build a bootable array using internal disk drives, ensure you install at least the
minimum number disk drives required to support the RAID level you want. See
page 31
for
more information.
Note:
Although you can connect both SAS and SATA disk drives to your SAS controller, Adaptec
recommends that you
not
combine SAS and SATA disk drives within the same array or logical
drive. See
page 66
for more information.
You have two connection options:
●
To connect directly to the controller, see the following section.
●
To connect to a backplane, see
page 39
.
Connecting Directly to the Controller
In a direct-attach connection, SAS or SATA disk drives are connected directly to a SAS card
with SAS cables.The number of direct-attached disk drives is limited to four per internal SAS
connector. (For more information about direct-attach connections, see
page 69
.)
